Data Structures and Algorithms

What is Data Structures and Algorithms?

Data Structure refers to a way of organizing data in a computer in such a way that it can be used effectively. There are several various data structures namely Arrays, Linked Lists, Stack, Queue, Graph, Hash Tables, etc. All data structures have their way use and requirement. The algorithm is a step-by-step procedure that is designed and defined as a set of instructions that is directed to be executed in a particular fashion for getting desired output for the given input. It is used for solving various problems involving the data. The algorithm is generally created in an independent manner of any required languages like C, C++, Python, etc. A particular algorithm can be implemented in more than one programming language.  

How do we use Data Structures and Algorithms in real-life?

Real life? Sure!

• Befriending someone on FB? Breadth First Search.

• Professor noticed and you running towards the exit? Depth First Search. 

• Waiting to board the bus? Queue. 

• Heard the word modesty and looking in the dictionary? Binary search. 

• Not sure about that and searching phone book for dad? Tree. 

• Filling your wallet with credit cards? Array. 

• Locating the car keys in a hurry? Hash.

Books Required

The main aim is to find complex topics with the easiest explanations and you probably won't be able to find that in one book only. Look for simple explanations in as many different books as possible. These are the books that I used to grasp the understanding of complicated topics covered throughout the syllabus. 

1. Introduction to Algorithms by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein. 

2. Python 3 Object Oriented Programming by Dusty Phillips.

3. Sams Teach Yourself Data Structures and Algorithms in 24 Hours by Robert Lafore

4. Algorithms Unlocked by Thomas H. Cormen
